FASTENING IEEANS' FQR WINDOWS.

Application filed July 21, 1917.

To all whom it may concern:

Be it known that I, WINTER WV. Mrnns, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Fastening Means forlVmdows, of which the following 18 a full, clear, and exact description.

The invention which constitutes the sub- Figure l is a verticalcross-sectional view of the ordinary Austral window showing my inventionapplied thereto.

Fig. 2 is an enlarged view of the meeting rails of the two sashesshowing my improvement also in cross section.

Fig. 3 is an end view of the fastening means.

Fig. 1 is a cross section thereof on the line -'l% of Fig. 2.

Fig. 5 is a cross-sectional view of the ordinary Austral windowillustrating a slightly modified form ofmy invention.

Fig.8 is an enlarged view thereof with parts broken away to showdetailed constructions of Fig. 5.

Fie'. 7 is a top plan view and Fig. 8 is an end view of the modifiedform shown in Fig. 5.

Fig. 9 is a perspective view of the construction shown in Figs. 1 to i.inclusive.

Referring to Figs. 1 to a in detail, the reference numeral 10designatesa frame in which the two sashes '11 and 12 are mounted, theformer being provided with sliding pivots at the top and the latter withsliding pivots at the bottom. These two sashes are pivotally connectedto balance arms 13 (one being shown) so that when one of said sashes ismoved the other is simultaneously moved with it. The details ofconstruction and operation will be clear from the prior reissue patentof E. G. Abell, No. 12,048, and

the patent to A.- Knox 8215510, to which reference is hereby made.

Located upon the meeting rail 14 of the lower sash is secured the basemember 15 of the fastening means. This member 15 is provided with ahorizontal perforation :16 throughwhich the secnringboltli is adapt-Specification of Letters Patent.

ed to project, the outer end of which is pro vided with a pivotedcamming or tightening member 18 and the inner end of which is providedwith a hook adapted to be cammed aipwardly by, and to engage over, thekeeper plate 19. The bolt 17 is provided with a shoulder 20, andinterposed between this shoulder and the base member 15 is a spiralspring; 21 which serves to maintain the bolt at its extreme inwardposition whenever the camming member 17 is in the dotted line positionshown in Fig. 2.

The base member 15 is provided with a counter-bore 22 so as to permit amovement of the inner end of bolt 17 in a vertical plane.

-F 2 shows the improved fastening means in normal position with thesashes closed. When it is desired to open the sashes any suitableinstrument is made to engage with the power of the spring 21, will bemoved inwardly to the dotted line position shown. If the movement of the(ramming member 18 is continued this movement will be im-- parted to theextension 23 and cause the inner end of bolt 17 to move sufliciently ina vertical direction to permit the said bolt and said keeper plate 19 tobe out of each others path of movement as the sashes are being opened.

From the above description it will be seen that when the sashes aremoved to closed position the member 18 will be in the dotted lineposition, illustrated in Fig. 2, and the engagement of the bolt 17withthe keeper plate 19 will be efiected automatically. After thisengagement the sashes cannot be opened from the exterior; in otherwords, they are locked in closed position. If it is desired. to open thesashes a downward pull from its dotted line position shown in Fig. 2 ofthe member 18 will be necessary; This downward pull of the member 18 isimparted to the extension 28 and results in an upward movement of theinner end of the bolt 17. On the other hand, if it is desired to effectan air-tight engagement between the meeting owingito the eccentricmovement ofthe ears 24 about their pivotal points, the base member 15and keeper plate 19 will be drawn toward each other, thus effecting acorresponding movement toward each other of the meeting rails of thesashes.

It is clear from the above description and the accompanyingillustrations that the improved latching device is particularlydesirable where the meeting rails are out of reach of the operator, asthe same are as readily operable by means of a suitable pole as they arewhen-manipulated directly by the hand of the operator. 4

In Figs. 5, 6, 7 and 8 is shown a modified form of the invention anddesigned to be used, for instance, where the windows are out of reach ofa hook. In this case the windows are opened by means of a cord 28attached to a member or arm. 25 which is secured to the hook 17 by meansof a suitable pin 26 which not only passes through said members 17 and25 but also through perforations 27 in the housing 15. When thusassembled the hook member 17 has only a pivotal movement about the pin26 as a center but it will be clear from the above description that theonly changes necessary in the substitution of the arm 18 for the arm 25is the provision of perforations 27 in the body 15 and a pinsufficiently long to have bearings in the perforations 27 in the hookmember 17. The opening of the windows is accomplished by exerting a pullupon the cord 28. When it is desired to close the windows it is onlynecessary to exert a pull upon the cord .29 which is connected to theouter sash, as will be understood. The spring 21 serves, as it does inFigs. 1 to 4 inclusive, to maintain the bolt member 17 in asubstantially horizontal position,that is to say, in substantially theposition as indi cated, for example, by the full lines in Fig. 6, thusenabling the said bolt member to automatically engage the keeper platewhen the sashes are moved from open to closed position.

What I claim is:
